Magers, Evanston, Ill; State Bank and Trust Company, Evanston, ill., a corporation of Illinois, trustee and executor of said Lloyd E. Magers, deceased, assignor, by inesne assignments, to Gaylord Bros, Inc., Syracuse, N.Y., a corporation of New York Filed ept. 15, 1961, Ser. No. 138,424- 11 Claims. (Cl. 211-44) This invention relates to a roll map support, and more particularly to a mobile stand which retains a plurality of maps so as to afford ready removal for use and which provides for elfective display of the maps in a desired position.

It has been the usual practice in school rooms and the like to place map-rails with roll-maps thereon just above the chalk blackboards. As a rmult, the maps have been ditficult to view because they were not sufficiently high above the floor in the rolled-down position thereof. Also, the maps covered the blackboards when thus exposed, thereby preventing full use of the blackboards for explanatory purposes or the like. And, securing the maps at the blackboards precluded close-up viewing and restricted the maps to a specific position. The present invention is a continuation-in-part of my copending application for Roll-Map Display Stand, Serial No. 87,424, filed February 6, 1961, now Patent No. 3,088,229, and overcomes the aforementioned difliculties by means of a roll-map display stand and/ or rack which provides for the retention of a relatively large number of rolled-up maps in the central areas thereof, by virtue of a continuous trough or support structure in the lower portion thereof, and coacting divider means in the upper portion thereof. Further, individual maps may be removed from their retained position on the trough structure and placed into a display position at a suitable height above the floor.

In accordance with the present invention, the means for maintaining the maps at a suitable height above the floor includes a specific bracket structure adapted to hold maps even of relatively large size and also to hold maps adapted to fit on a tripod stand. This bracket structure is releasably positioned on upright tubes which are telescopically received in complementary and larger frame tubes for the stand, and the height of the upright tubes is adjustable so that the maps may be placed at a desired elevation for display.

Further in accordance with the invention, map-rails for mounting the maps are secured to the bracket structure. Thus, the bracket structure includes a pair of angularly formed bracket extensions having upper parallel arms and depending extensions adapted to fit within corresponding adjustable upper tubes as described. The horizontal arms have integrally formed therewith an outer depending portion apertured to receive bolt means securing an upper map-rail thereacross. inwardly and downwardly angled portions extend parallel with the adjustable upper tubes and are buttressed thereagainst by bolt means securing a lower pair of map-rails across the downwardly disposed angled portions, with upper bolts being receivable in a corresponding registered aperture in an adjacent adjustable upper tube and with the lowermost bolts having suitably formed nuts engaging the adjustable upper tubes in supporting relation, thereby to accommodate Weight imposed on the bracket structure by maps secured on the map-rails.

In order to mount maps on the map-rails, the maprails are spaced slightly outwardly of the bracket structures and thus are adapted to receive slide elements or chart heads to which the maps are secured. So as to provide for mounting of a roll-map or chart head for a tripod stand, the upper map-rail structure has an inner elongated bar secured between the upper outwardly extending portions of the bracket structure and a pair of shorter outer bars secured by bolt means to the inner elongated bar in proximately spaced parallel relation thereto. The outer bars or rail portions are spaced apart centrally and axially thereby to define an opening therebetween such as to accommodate the bracket for a tripod chart head. If a solid track arrangement were provided, the chart head bracket would prevent the head from being mountable thereon. Thus the chart head bracket can fit freely in the space between the two rail portions described. The tripod chart head is hooked over the upper bipartite rail, and the slide-on feature is therefore not used in this application of the device. Of course, the top rail can also accommodate slide-on heads that are not obstructed by the presence of brackets.

The support or stand of the invention may also be provided with rollers for ready movement from one position to another, and may have other advantages as set forth in the copending application above referred to.

Accordingly, it is an object of the present invention to provide a roll-map stand having a bottom trough support portion extending uninterruptedly thereacross and which will not only support maps and the like in cooperation with upper divider means therein, but because of the fully solid bottom and corrugated rubber top pad provided, will accommodate other display devices in supported relation in the rack such as manikins, globes and the like.

Another object of the invention is to provide a map support structure as described having an upper rail which is split centrally to accommodate a chart head bracket for a tripod mounted chart head or map head.

Other objects and advantages of the invention will become apparent as the description proceeds in accordance with the drawings in which:

FIGURE 1 is an end perspective view of a roll-map support stand according to the present invention;

FIGURE 2 is an enlarged end view, partly broken away, of bottom tray or support means for maps, manikins, globes and the like to be held in the stand of the invention;

FIGURE 7 is a corresponding view showing a further form of slide means to be used with the bracket means and map-rail structure according to the invention; and

FIGURE 8 is a bottom plan view, partly broken away, of a portion of the bracket structure in operative relation with a tripod chart head.

Referring now to the drawings, and to FIGURE 1 in particular, a roll-map support stand i is shown which comprises a plurality of frame tubes l1, l2, l3 and 14, a base 15 secured to the frame tubes at the lower end thereof, a grid 16 secured to the frame tubes at the upper end thereof, upper tubes 17, 18, 19 and Z0 adjustably and telescopically disposed in the tubes 11 through 14, and rollers 21 on the bottom ends of the tubes 11 through 14. As best seen in FIGURE 3, pins 22 are selectively positionable in vertically spaced orifices 23 so as to hook over the adjacent upper ends of the frame tubes.

In order to support maps for selective elevation, a bracket structure 24 is provided according to the invention which includes a pair of brackets 25 releasably mounted on a corresponding pair of preferably longitudinally aligned upper tubes, or on both such pairs of the upper tubes. Map-rail structures 26, 27 and 28 are mounted in superposed, parallel relation across the brackets 25, as also hereinafter described, to support maps as indicated at 29, 3t) and 31 on slides or chart heads 32, 33 and 34.

The individual pairs of frame tubes 11 through 14 have their lower ends turned outwardly away from each other and then downwardly to provide a highly stable construction for the stand, with the base 15 preferably being secured at a relatively wider portion of the stand thus provided. The base 15 is formed as a continuous support extending across the bottom of the stand, in accordance with the invention, so as to accommodate various objects and materials in addition to maps in readily accessible position therein. The base 15 may include outwardly and downwardly extending marginal edges 35 and 36 as seen in FIGURE 2, having nuts or the like 37 brazed therein to receive heavy duty screws 38 at each end of the trough. Other constructions for supporting the trough may also be utilized within the scope of the invention, and so as to connect the uprights in parallel spaced relationship.

The base 15 also includes side portions 39 and 4t] and a bottom 4-1, as well as end flanges or other transverse rigidifying means 42 and 43. Side portions 3% and 4iia may be provided opposite the side portions 39 and 49 to form side troughs for roll maps or the like and the base portion between these troughs is suitable for supporting instructional materials such as manikins or globes, as described. Connecting means 37a and 38a may be utilized adjacent the side portions 3% and a which are similar to nut and screw elements 37 and 38 so that an exceptionally rugged reinforced base construction is provided. A ribbed rubber mat 44 overlies the bottom 41 in a preferred form of the invention, although other anti-friction covering means may be utilized in this connection. Thus the individual maps may be held in supported relation on the base 15, together with accessory materials and articles, without any hazard that they will inadvertently fall out of the stand.

The base or trough 15 cooperates with the grid 16 to afford a rack and support means for storing or holding maps until such time as they are displayed on the maprails. To this end, the grid may include a pair of transverse bars 45 and 46 secured to the respective frame tubes or uprights 11 and l4, l2 and 1'13, by suitable means which may include bolt structures or the like (not shown) and longitudinally extending support bars 47 and 48 are connected between the transverse bars 45 and do in parallel relationship and in predetermined spaced relation to the frame tubes. The longitudinally extending support bars 47 and 48 provide a support structure for a plurality of divider elements which are indicated generally by reference numeral 49. The divider elements 49 are disposed in parallel, spaced apart relationship, with the spacing therebetween preferably being such as to accommodate maps of various sizes as desired, and these elements preferably extend equally on opposite sides of the bars 47 and 48 so that individual maps, such as the map 56 shown in FIGURE 1, may be received between the extending ends of adjacent divider elements as shown.

The upper tubes 17 through Ztl may be vertically adjusted by means of the pins 22 as indicated. As a result, correspondingly aligned upper tubes may be set at a suitable elevation for placing a bracket structure 24 and a map thereon in a position where the map is well i spaced from the floor, thereby giving full visualization thereof to students or other viewers.

The brackets 25 of the bracket structure 24 each includes a horizontally extending arm portion 51, a downwardly extending portion 52 and an offset end flange 53. Thus the portions 52 and 53 constitute insert means for the upright upper tubes which engage within the upper tubes as seen in FIGURE 4 and support the arm portions 51 in horizontal position as engaged by the upper ends of these tubes.

Further, the brackets 25 include outer downwardly extending abutment portions 54, at the ends of the arm portions 51 opposite the insert portions 52 and 53, inwardly and downwardly extending portions 55 approaching the portions 52 and 53, and vertically depending abutment legs or buttressing portion 55 adapted to extend in parallel proximate relationship to the upper tubes when the brackets are assembled therein as shown in FIGURES 3, 5, 6 and 7.

The vertical portions 54 and legs 56 of the brackets 25 are apertured at 57, and at 58 and 59 respectively; and the map-rail structures 26, 27 and 28 are thereby secured to the brackets by means of bolts 6t), 61 and 62, as seen in FIGURES 3 through 5, which extend through the corresponding apertures 57 through 59.

In accordance with the invention, the upper rail structure 26 is secured in cantilevered fashion above the lower map-rail structures 27 and 28, and in outwardly spaced relation thereto, as hereinafter further described. The upper rail structure 26 includes an elongate bar or rail portion 63 secured by the bolts 6% to the depending portions 54 and a pair of outer rail portions 64 and 65 secured at their outer ends to the rail portion 63 by the bolts so, as best seen in FIGURE 5. Preferably, spacer elements 66 are disposed between the elongate rail portion 63 and the outer portions 64 and 65 in surrounding relation to the bolts 6G. Further, bolts 67, similarly provided with spacer elements (e.g. at 66:!) secure the inner, adjacent ends of the rail portions 64 and 65 in fixed parallel relation to the rail or bar 63. Thereby, the rail portions 64 and 65 define a gap centrally which is indicated by reference numeral 68. The bolts as may have suitable end nuts 69 thereon and the bolts 67 may be riveted in position on the elongate bar or member 63.

The bolts of secure the map-rail structure 27 across the vertical portions 56 of the brackets 25 and the maprail structure 27 is maintained in spaced relation thereto by means of spacers 7t? surrounding the bolts 61. Suitably configured nuts 71 are threaded onthe bolts 7% and against the vertically depending leg portions 56 and are disposed in abutting engagement with the adjacent upper tubes such as the tube 19 shown in FIGURE 3. The adjacent upper tubesdefine registered openings 72 receiving the outer ends of the bolts of, to accommodate exceptionally heavy map structures. Thus, map manufacturers may utilize a three inch steel backboard or slide structures with maps secured thereto on large spring rollers corresponding to window shade rollers, as hereinafter set forth, and the structures to be thus supported are relatively very heavy so that the arm brackets could otherwise be pulled downward. The nuts 71 may be octagonal, and rest firmly against the upper tubes to assist in supporting the weight, and the bolts 61 threaded therethrough are relatively long, as described, to take-up the pull-down strain due to the heavy map-roll structures and thereby to prevent bending of the arm bracket structures.

The bolts 62 support the map-rail structure 28 with a spacer or bushing 73 interposed between the map-rail structure and the depending portion 56. It will, of course, be appreciated that fewer than the three maprails shown may be utilized although more map-rails may also be provided. In the embodiment shown, it is desirable to secure the depending portion 56 against a support, and the bolts 62 are provided with end nuts 74 which may be of an acorn-nut construction, if desired, and which rest against the adjacent upright upper tubes.

It will be appreciated that an advantage resides in the provision of the lower abutment nut elements 74 since these nut elements may engage the lower upright tubes as shown in FIGURE 6 to position the maps for viewing without the use of pins such as the pins 22. If the lower map-rail and map were eliminated, a similar abutment member corresponding to the acorn nut '74 would still be a feature of the invention to provide support for the brackets 25 in cooperation with the upper tubes against which the said nuts 74 abut.

Although the holes or openings 23 are shown as being drilled on the front or outside of the upper tubes corresponding to the position of the holes 72, the holes 23 may also conveniently be disposed on the back or inner sides of the upper tubes, in the operative position thereof, and spaced, for example, 4 inches apart for receiving the pins 22 to hold the upper tubes and the map-rail structures at a desired elevation. Preferably, the uppermost openings 23 are positioned in the upper tubes to prevent the upper tubesfrom dropping down into the curved portions of the lower upright tubes.

A round or square piece of wood may be dropped down into the lower upright tubes to prevent the upper tubes from accidentally dropping down into the curved portions and against the casters before the shaped pins 22 are placed in the holes 23.

The slides 33 and 34- constitute backboard structures for the maps 30 and 31, and are configured and dimensioned with a preferably U-shaped construction to slide endwise onto the respective map-rail structures 27 and 28, from either end as desired.

The maps 30 and 31 are supported on the backboard structures or slides 33 and 34 by suitable brackets 76 and 77 and trunnions 78 and 79, as understood by those skilled in the art, so that the maps may be unrolled in the manner of a window shade.

The upper map structure 29 is mounted on a chart head or backboard slide 32 which is adapted to be supported on a tripod. Thus, the slide or backboard 32 has secured therein a bracket 80 with a vertical axial opening 81 to receive the upper end of a tripod structure, and the bottom flange of the slide is apertured at 81a in register with the opening 80 so that the bracket 80 may seat against a suitable flange or other construction on a tripod in supported relation, when desired.

It will be appreciated that if the track structure 26 were a solid track arrangement, the bracket 80 in the chart head 32 would prevent the head from being mountable thereon. Accordingly, the invention provides the gap 68 between the outer rail portions 64 and 65 to accommodate the bracket 80. Thereby, the bracket 8t) can fit freely in the space between the two rail portions.

Also in accordance with the invention, the chart head 32 has a G-shaped cross-sectional configuration with the transverse dimension being substantially greater than the transverse dimension of the outer map-rail portions 64 and 65 of the map-rail structure 26. Thereby, the chart head may be flipped over the outer rail portions with the bracket 80 between the said portions and in the gap 68. Thus, the slide-on feature of the lower slides 33 and 34 is not used for the bracket equipped chart head 32. Of course, it will be appreciated that the top rail structure 26 could also accommodate slide-on heads which are not obstructed by the presence of brackets.

Referring now to FIGURE 6, a slide or backboard con.- struction 82 is shown for supporting maps fastened to a large roller window-shade structure, which structure is relatively quite heavy. Thus, the outside diameter of such a roller Window-shade structure, in the rolled condition thereof, may be 3 inches. The backboard 82, which may be made of steel or other suitably rugged material, has an upper hook portion 83 and a straight depending portion dimensioned to rest against the lower rail structure 28 while the upper hook portion 83 is hooked over the upper rail structure 27. The backboard or slide 82 may also be utilized where large heavy assemblies of several maps are to be accommodated on the brackets 25.

Referring now to FIGURE 7, another embodiment of the invention is shown wherein a backboard or slide 84- is slidably mounted on the rail structures 27 and 28 but has upper and lower hook portions 85 and $6 so that the dual rail structures 27. and Z? coact in the manner of a single rail structure while being available for positioning maps individually thereon, alternatively to the positioning of a backboard or slide such as the slide 84-.

It will thus be appreciated that I have provided a map support which is simple, rugged, and attractive in appearance, and may be used in a variety of institutional situations including the schoolroom and other locations where ready access and high visibility are desirable. Thus, the support structure or stand it may be moved to any desired position in a classroom or the like, and the maps themselves may be raised and lowered in accordance with the size of the maps or other conditions, without difficulty.

The provision of a large trough or base 15 increases the flexibility and usefulness of the support or stand 10, since articles in addition to maps may be stored, such as globes, manikins, books and other objects. At the same time, the maps will be supported reliably in the grid 16 both'by virtue of the grid structure itself and the corrugated antifriction characteristic of the base or trough 15.

The cantilevered, hook-like shape of the brackets 25 assures that the upper maps will be solidly supported so that they overlie the lower maps and thereby may be displayed in conjunction with display of the lower maps. And the support of the brackets 25 is buttressed by the engagement of the depending portions 56 with the upper tubes and with the connection between the brackets and upper tubes alforded by the bolts 61 which extend into corresponding apertures in the upper tubes.

Thus, a stand of very great utility has been provided which is adapted for a wide range of applications.
